your router is in Privileged EXEC
mode?

Router>

You
have connected to your Cisco router
through a Telnet connection. To
test one of your connections,
you use a debug
ip packet command.
Even though you are sure traffic
is passing through your router,
nothing is reported in your terminal
window. What is the most likely
cause of this problem?

There
is no debug
ip packet command.

You
need to type in the terminal
monitor command
to see debug output from a Telnet
session.

This
command displays information
only if the interface experiences
trouble. No output indicates
that the interface is fine.

Cisco
routers do not allow you to
enable debug commands
remotely due to security restrictions.

Your
routers at ACME, Inc., are having
some connectivity issues. You
issue show commands
for each connecting router's
interface. Why are they unable

You
are configuring your router and
type in an Enable password
and an Enable
Secret password.
Your fellow network technician
asks you why you have two passwords
set when you need only one. What
do you tell him?

The Enable password
is used by low-level applications.

If
you reverted to an older version
of the IOS, it would not understand
the Secret password.

Both
passwords are treated the same.

It
is a failsafe method of ensuring
that people need to type two
passwords instead of just one.

the recalled command. You notice
your up- and down-arrow keys do
not function because you are using
an older terminal program. What
command combinations could you
use to recall the previous command
and move your cursor to the beginning

does
this
mean?

did not enter enough characters
for your device to recognize
the command.

You
did not enter all the keywords
or values required by this command.

You
entered the command incorrectly.

Context-sensitive
help is unable to help you with
this command.

You
are typing a command into the
Cisco IOS. It is more than one
terminal line long. What will
the IOS do?

The
router automatically moves the
cursor to the next line and
uses a caret (^) to indicate
the line break.

The
router truncates the command
because commands longer than
one line are not allowed.

The
router automatically scrolls
the line to the left and uses
a dollar sign ($) to indicate
that there is text to the left
of the $.

router shortens all the commands
to squeeze the command on to
the screen.
